New Zealanders are getting fairly philosophical about it now. Several people have said that they'd not have wanted to have the World Cup if they had to have it via an effective double tie. The general feel from most is that they'd rather not have New Zealand jumping around holding aloft a World Cup with a boundary count-back as the manner of victory. Many thoughts seem to be that this will not age well over time, and people would rather not have the World looking back during all future world cups and despite the fantastic game and contest, point the finger at New Zealand being the most dubious holders ever with Zero runs between the teams.
Several others have said that T20 has had far too much of an effect on 50 over rules. Runs, had their time to decide 50 overs of contest. They were equal. Runs had their chance to decide a super over. They were equal. There's plenty of people who felt it odd that wickets got zero look-in in such rules, seeing as the game is supposed to value the bat and ball equally.
Plenty of scope for mockery from neutrals who've actually outright won a world cup (all of them) and I'm sure England will do better than New Zealand at deflecting such comment.
